The blonde star, 19, joined her co-stars in London for the glitzy bash, and got stuck into the theme of all black everything.

Showing off her super slim figure, the youngster looked all grown up as she posed for the cameras.

Teetering in huge heels, Lorna towered above the crowds and showed off a hint of midriff in the cut-out one-piece.

And she wasn't the only one stunning in black for the event this evening.

From Hollyoaks' Jorgie Porter, to Gemma Atkinson and Charley Webb, the stunners pulled out varying shades of dark as they embraced the end of winter in London.

Jorgie showed off her bare midriff in a cut-out outfit, wearing a thin bandeau over her boobs and a sheer lace skirt to match.

She added high strappy sandals for the out-there look, a new style for the usually revealing star.

Meanwhile Emmerdale's Charley opted for a skintight black number, showing off every inch of her toned legs.

With her long blonde hair loose and huge, she couldn't help but turn heads next to her co-stars.

Gemma Atkinson followed suit in a tight black jumpsuit, showing off her tiny figure and a glowing tan.

The star looked over the moon to be there, and flashed a huge grin as she wore her hair styled up with plaits.

She was joined by Emmerdale's Verity Rushworth, who returned in a strappy number and high heels, revealing a hint of cleavage in the cute ensemble.

But one star not letting anything hold her back when it came to the style stakes was her co-star Michelle Hardwick.

While she also opted for a short black dress, this time wearing it off the shoulder, she coupled it with thigh-high black boots, taking the risk factor way up to Jennifer's levels - after she wowed in red PVC.
